Simple Answer:
The definition of a current is a collection of moving charges.
Hence for current to flow, one needs charge and one needs it to move.
Electric current flows when charge move - that is the definition.
Long Answer:
One generally sees current flow on Earth with a conductor and a voltage or potential difference that creates and electric field and charges in the conductor feel a force and move creating current.
The conductor may be a wire and the charges may be electrons.
The conductor might also be water with dissolved salt and the electric field causes the salt ions to move and it is the moving ions that constitute the current.
If you are the Sun and you are producing electrons and protons on the solar wind, then complex electromagnetic fields may have ejected the charges from the sun, but the current that is the charge moving through space is maintained just by the inertial of the particles. You don't need an electric field to maintain the current and you don't need a conductor to hold the charges.
For a current to flow, you need net charge moving. That is all. Current is technically charge density times velocity.

Is the amount of current that flows in the wire of electric circuit the same as the current that flows in the filament of the light connected in that circuit?
yes
What is the name of the electric current which always flows in the same direction?
Direct current (DC) is the name of the electric current that always flows in the same direction. It is commonly used in electronics and power transmission systems.
What type of energy flows through a wire?
Electric energy flows through a wire when an electric current passes through it.
What is the name of an electric current that flows in one direction?
That's a "direct" current.
What do you call the complete path that an electric current flows through?
The complete path that an electric current flows through is called an electric circuit. It includes components like wires, switches, and resistors that allow the flow of electricity in a closed loop.
What is the path that electricity follow?
An electric current flows from negative to positive.
When an electric current flows though a wire it creates a what around the wire?
When an electric current flows through a wire, it creates a magnetic field around the wire. This magnetic field forms concentric circles perpendicular to the direction of the current flow.
